Though nothing is really wrong with it, and having two Traits in here to get the Healing Power discount is good, thats about as we would go with Watcher of Resolve. The later buffs deserve a cool reception.
When it comes to the Protector of Song, the first buff, from having two Traits slotted is kind of lame: a cool-down reduction on Call to Greatness. But add a third and the effects from your Ballads last an extra ten seconds. You should think about all the Ballads you have and buffs they give you the best knight gold.
Four traits get your Improved Tales. It is great to have better ones to choose from since you should always have a Tale running. And the Legendary Trait it opens is beautiful. It combines your four existing, improved Tales into two. The new combo Tales (of Warding and Heroism and of Frost and Flames Battle) give you the full buffs from both of their constituent Tales, for just an extra point of Power per second. Youll need to finish Book 2.6.7 to earn the Legendary, but anyone who groups with you will think its worth getting you the Tales so they can have the buffs.
